I think I am confused about the need for this PR . Doesn't the `RepartitionExec`operator already implement N : M re-partitioning? https://github.com/apache/arrow-datafusion/blob/master/datafusion/src/physical_plan/repartition.rs#L65-L76 https://github.com/apache/arrow-datafusion/issues/112 is a pretty old ticket from @andygrove and it may actually predate `RepartitionExec` I almost wonder if we could remove `CoalescePartitionsExec` entirely and replace all uses with `RepartitionExec` (with output partitioning of 1)?
